Go to the city of Anvil, then go to the inn. Inside is a man whose name starts with a "B". He is selling his grandfather's old manor. You can purchase it for 5,000 gold, which is very cheap considering that most houses are 15,000 gold and are not as good. The house (at first) is ugly and haunted. However, after completing the quick quest the house will be fixed up without any additional payment.
